About the role
The API Architect is responsible for defining and driving Expereo’s end‑to‑end API strategy and architecture, shaping the standards, guardrails, tooling, and operating models that power our unified customer and supplier experiences. This role leads the harmonisation of our API landscape into a modern, secure, reliable, AWS‑native API platform built on consistent patterns and automated compliance.
The architect owns the evolution of API Gateway patterns, identity and access models, service templates, paved‑road pipelines, SDK foundations, and governance. They ensure that every API shipped by any team adheres to a harmonised contract‑first model, backed by mature observability, reusable Terraform policy packs, industry‑aligned standards (e.g. MEF LSO), and scalable integration patterns.
This is a hands‑on architectural role. It requires someone who understands deep platform engineering, who can architect, prototype and implement, and who can work across domain teams to ensure APIs become first‑class, product‑grade capabilities across Expereo.
Key Responsibilities
API Architecture Ownership
Own the target API architecture across all domains, ensuring alignment with Expereo’s AWS‑native, contract‑first, policy‑as‑code approach.
Define and evolve API Gateway patterns, policy packs, Terraform modules, routing models, domain boundaries, and multi‑team safety mechanisms (path ownership, delegated deployment).
Lead the migration from today’s fragmented API estate to a harmonised platform using building blocks such as AWS API Gateway, ALB, Cognito, AWS Sig V4, and Event Bridge.
Standards, Governance & Contract‑First Design
Define and maintain API standards covering Open API specification, versioning, naming conventions, error taxonomy, schema governance, and change management.
Establish compatibility checks, contract linting, consumer‑afety rules, and automated CI gates.
Ensure APIs publish consistent metadata, SLOs, lifecycle state, scopes, and machine‑readable manifests into the catalog.
Identity, Security & Policy Enforcement
Architect the identity model with Cognito OIDC for external consumers and AWS Sig V4 for internal services, including scope and claim models, key rotation, and partner onboarding flows.
Own API Gateway security posture via reusable policy packs: schema validation, rate limiting, WAF rules, OAuth2/OIDC wiring, logging, and sanitisation.
Define secure patterns for webhooks, third‑party integrations, and real‑time delivery.
Platform Enablement & Paved Road Ownership
Architect and maintain polyglot service templates (. NET, Python, Type Script) shipped with batteries‑included auth, telemetry, retries, validation, CI pipelines, and SDK generation.
Ensure the paved road remains simple, opinionated, and scalable while providing documented escape hatches.
Integration & Messaging Architecture
Define standard patterns for inbound and outbound integrations, including retries, backoff, circuit breaking, schema registry usage, event‑driven choreography, and outbox pattern adoption.
Ensure API and event schemas remain interoperable, versioned, and backwards‑compatible.
Observability & Reliability
Establish API observability baselines using Elastic APM/OTEL, structured logging, golden dashboards, SLOs, and synthetic checks embedded in the standard pipeline and templates.
Ensure critical API flows, such as quoting, ordering, delivery tracking, and supplier interactions, are observable end‑to‑end.
Technical Debt Leadership
Guide remediation of systemic issues, including dependency updates, caching redesigns, API composition cleanup, and security posture fixes.
Ensure legacy APIs progressively align with the new operating model via migration guides, adapters, and compatibility layers.
Cross‑Functional Leadership
Partner with domain teams, product, security, SRE, and engineering to embed paved‑road patterns and ensure consistent adoption.
Lead design reviews, support RFC/ADR governance, and champion API product thinking across the company.
Technical Expertise
Demonstrated experience designing and operating scalable API platforms using AWS API Gateway, ALB,, Fargate/ECS, Cognito, IAM, and Event Bridge in combination with one or more of these stacks:. NET Core C#, Python and/or Type Script.
Strong expertise in contract‑first API design using Open API and/or Graph QL, with deep knowledge of versioning, compatibility rules, and schema governance.
Solid understanding of authentication and authorisation patterns, including OAuth2/OIDC, JWT, AWS Sig V4, scopes, claims, and partner onboarding flows.
Hands‑on experience with infrastructure‑as‑code (Terraform preferred), including reusable modules and policy packs.
Strong knowledge of modern Dev Ops and CI/CD practices, automated quality gates, security testing, and dependency scanning.
Solid understanding of event‑driven patterns, message routing, schema registries, DLQs, and outbox patterns.
Experience with observability tools (Elastic APM or similar), SLO‑driven operations, and synthetic checks.
Architecture & Design Skills
Ability to define and evolve platform‑wide architectural standards and guide large‑scale remediation.
Strong experience creating opinionated templates and paved‑road tooling for engineering teams.
Ability to decompose monolithic back‑ends into domain‑aligned API boundaries and integration patterns.
Security & Quality
Proven ability to architect secure, standards‑based identity flows across internal and external consumers.
Strong knowledge of API edge security, rate limiting, schema validation, WAF patterns and least‑privilege design.
Collaboration & Leadership
Strong cross‑functional communication skills, able to influence product owners, engineers and executives.
Experience leading multi‑team initiatives and driving adoption of architectural standards across an organisation.
Ability to mentor teams and embed architectural patterns through documentation, enablement, and example implementations.
Mindset
Builder mentality with a hands‑on approach.
Pragmatic but uncompromising on security and contract integrity.
Advocates automation over manual governance and paved‑road adoption over one‑off exceptions.
Comfortable modernising legacy systems gradually while designing for the future.
